Description

{Entrance parts for standard plastic garbage bag in a vaccum refuse collection system}

The present invention relates to a pay-as-you-go garbage bag input device having a structure suitable for an air transfer type garbage collection system in which a pay-as-you-go garbage bag is used.

The air transfer type garbage collection system embeds a transfer pipe between a garbage dumphouse and each building in an area with a large number of buildings such as an apartment, an officetel, a commercial complex, a residential complex, and the transfer pipe is disposed of garbage for each household or each floor. While connected to the end tube extending vertically to be connected to the inlet, while periodically connected to the air flow by the vacuum inside the connected tube by the user to dump the garbage bags temporarily stored by the user to collect at once It is a system.

In such a garbage collection system, an input port for dumping garbage bags by the user should be equipped with a function to satisfy the following several conditions.

First, it should be possible to completely prevent the spread of odor from the garbage bag temporarily stored in the end pipe to the residential area through the inlet.

Second, it should be possible to drop only one garbage bag at a time to prevent unjust dumping.

Third, since it is a facility for hateful facilities, it should be possible to minimize externally exposed parts.

 [0003] An input device applied to a conventional known waste collection system is configured to form an injection hole as a whole by a bucket disposed separately above the upper end of the end pipe, and the bucket includes a drum for rotating the motor as a power source. At the same time, a through tube is provided in the radial direction of the drum to form a substantial inlet. The through tube is to open or close the inlet opening according to the rotation of the drum, and the lower side of the drum is configured to have a valve plate operated by a separate driving source. In such a configuration, the user puts the waste bag into the through tube and removes the drum. When rotated 180 degrees, the lower valve opens and the garbage bags put in the through tube are naturally dropped and collected. (See Patent Document 1)

As another example of the input device, the inlet opening and closing device and the volume limiting cylinder opening and closing device is arranged up and down at the upper end of the end pipe and connected between them by a link so that the opening and closing device and the volume limiting opening and closing device to open and close oppositely. When the user dumps the garbage bag with the opening opening / closing device, the volume limiting container opening and closing device is closed so that only one garbage bag can be dumped. The garbage bags dumped as they are opened are collected naturally. (See Patent Document 2)

In addition, some input devices detect the garbage bags on the pay-per-use identification system to unlock the garbage inlet doors, and when the foot switch is pressed, the safety cover rotates downward to close the inside of the end pipe. It is also known that the waste bag is opened to be dumped, and when the foot switch is released after dumping, the inlet door is closed again, and the inner safety cover is opened while the waste bag is dropped and collected. (See Patent Document 3)

As another example, when the garbage inlet is opened by sliding the door downward by the user's operation, the safety cover 16 rotates downward to close the passage in the inside of the end pipe, and in this state, the user opens the garbage bag. If the operation is put into the garbage inlet and closed again, the door slides upward to close the garbage inlet, and at the same time, the safety cover is moved upward from the inner side of the end pipe to open the passage, so that the garbage bag is naturally dropped and collected. Devices are also known. (See Patent Document 4)

[Patent Document 1] Korean Patent Registration No. 10-0753482, Figure 2b [Patent Document 2] Korean Patent Registration No. 10-0858209, Figure 2b [Patent Document 3] Korean Patent Registration No. 10-0874845, Figure 2a [Patent Document 4] Korean Patent Registration No. 10-0945847, Figure 5

In the apparatus disclosed in Patent Document 1, a considerable width must be secured so that the drum can be rotated, so that the installation space can not be reduced to a minimum, and there is a disadvantage of separately preparing a drive source for rotating the drum and a drive source for valve operation at the lower side thereof.

The devices disclosed in Patent Documents 2, 3, and 4 have a structure that can be installed even in a narrow space, but the doors exposed to the outside and the doors disposed inside are opened and closed in opposite directions so that they are simultaneously opened for a predetermined time during the opening and closing operation. There is a problem that odor comes out from the garbage bags collected inside.

It is an object of the present invention to provide a pay-as-you-go trash bag input device that can be disposed in a minimal space by a structure for transporting and storing the dumped garbage bags in a vertical direction.

Another object of the present invention is a pay-as-you-go agent which can shorten the time that the odor is propagated to the outside during the dumping of the pay-per-use garbage bag by the configuration in which the bottom portion closing the bottom of the space in which the garbage bag is stored is quickly opened and closed near the lowered position. To provide a garbage bag input device.

The pay-as-you-go garbage bag injector of the present invention comprises an outer cylinder having a liner with a cam plate attached to its inner side in the center thereof, and an inner side of the liner is provided with an inlet to slide up and down in an axial direction. The lower end of the outer surface of the storage container is attached to the mounting band extending to the outer periphery of the bracket and the bearing unit, while the bracket is connected to the yoke that is stretched from the drive source to move the housing up and down, and the In the bearing part, the arm is connected to the shaft so as to rotate, and at the free end thereof, a cam roller is disposed to roll the cam plate, and the arm is integrated in a bottom door that opens and closes the bottom of the storage container. By attaching and fixing to the position of the bottom surface in accordance with the position where the storage container linked to the drive source is moved up and down Shut may be implemented using a configuration in which the door is open or closed.

In addition, in the above-described configuration, when the outer circumference portion of the bottom door is formed to extend more than the outer circumference of the storage container, the arm is attached to and secured to a sufficiently large area so that the bottom door has a rigid structure. Can be installed.

In addition, when a balance guide and a guide shoe guided through the liner are interposed between the liner and the housing, the lifting movement of the housing by the driving source is performed in a balanced state.

In addition, the opening and closing time of the bottom door is limited by the cam roller rolling on the cam plate of the liner, so that the surface of the cam plate is formed of the upper part of the relatively long vertical surface, the middle part and the lower part of the relatively short length, It is preferable that the middle part is formed as a concave part by an inclined surface extending from the top and bottom, respectively, so that the bottom door opening time when the storage container is moved up and down is shortest.

In addition, when the balance guide is provided on the inner side of the liner, it is preferably arranged in a position perpendicular to the cam plate.

The pay-as-you-go garbage bag input device of the present invention is arranged by placing a storage container guided by a liner to move up and down inside the outer cylinder, and installing a bottom door at the bottom thereof, so that the bottom door is opened or closed according to the lifting position of the storage container. Since all structures are arranged in the vertical direction, the width of the device exposed to the ground can be minimized.

In addition, the bottom door has a structure that is opened or closed in conjunction with the cam roller rolled on the fixed cam plate attached to the inner surface of the liner during the lifting and lowering movement of the storage container, so that the lower side of the storage container during the dumping of the pay-per-use garbage bag It is possible to shorten the open time of the terminal tube to be opened to the outside through the shortest, thereby actively suppressing the spread of odor emitted from the pay-per-use garbage bags temporarily stored under the terminal tube to the ground.

It will be described below in detail as a preferred embodiment according to the accompanying drawings, the metering bag garbage injector according to the present invention.

Figure 1 is an exploded perspective view showing the main part of the present invention, the outer cylinder (2) which is provided on the ground is the inner end of the end pipe of the end pipe constituting the conventional air transfer type garbage collection system buried in the ground ( (Not shown).

Inside the outer cylinder 2, a liner 4 is inserted in the axial direction and integrally attached. Moreover, the liner 4 is provided with the balance guide 6 and the cam plate 8 in the inner surface, and these are attached and fixed so that they may be parallel to an axial direction, respectively.

The balance guide 6 and the cam plate 8 may be arranged to be perpendicular to each other.

Inside the liner 4, the storage container 10 is fitted to be slidable in the axial direction. The storage box 10 is formed of an inlet 12 opened on one side of the outer surface to receive a pay-as-you-go bag, and the bottom is open, whereas the top is finished with a trimming panel 14.

The bottom door 18 is arranged to be opened and closed by the mounting band 16 at the lower end of the outer surface of the storage container 10. The mounting band 16 is provided with a bracket 20 on the side, and the bracket 20 is connected to a yoke 24, which is expanded and contracted by a driving source 22 such as a pneumatic cylinder, so that the housing 10 is axially oriented. It is supposed to link up and down.

The drive source 22 may be a spindle motor having a rack and pinion instead of a pneumatic cylinder, in which case the rack is attached to and fixed to the inner side of the liner 4 and the spindle motor is attached to the outer side of the housing 10. The pinion of the output shaft is attached to the rack and the gear is engaged, but the installation space is larger than that of the pneumatic cylinder, and the structure is complicated.

The upper portion of the outer cylinder (2) can be closed by the trimming panel 14 of the housing 10 fitted to the liner (4), but the edge is a separate ring 26 is fitted and finished.

On the other hand, the mounting band 16 is provided with a bearing portion 28 extending separately from the bracket 20 in order to hinge the bottom door 18, the bearing portion 28 has a bottom as shown in Figure 2a An arm 30 fixedly attached to the door 18 is rotatably connected by a shaft 32, and a cam roller 34 is provided at the free end of the arm 30. As shown in FIG.

As shown in FIG. 3, the shaft connection structure of the bottom door 18 to the lower mounting band 16 of the storage container 10 extends a portion of the outer circumference of the storage door 10 more than the outer circumference of the storage container 10. It is desirable to allow the arm 30 to be attached to the bottom surface of the bottom door 18 in a sufficiently wide area.

On the other hand, the storage container 10 is equipped with the guide shoe 36 in the position facing the balance guide 6 of the liner 4, and this storage shoe by the said drive source 22 by this guide shoe 36 is carried out. The lifting movement of 10 is performed smoothly in a balanced state.

Since the cam roller 34 provided in the bottom door 18 always rolls on the surface of the cam plate 8, the apparatus of the present invention opens and closes the bottom door 18 in the shape of the surface of the cam plate 8. You can control the timing.

More specifically, as shown in Figure 4, the upper surface (A) and the lower portion (C) of the cam plate 8 is formed in the vertical plane of the same level, and the middle portion (B) is the upper portion (A) and the lower portion ( When formed in the inclined concave portion in C), the length of the middle portion (B) corresponds to the opening and closing time of the bottom door (18).

An opening and closing operation example of the bottom door 18 will be described with reference to FIGS. 2A to 2C.

2A shows an example in which the housing 10 is lifted up by the drive source 22 and the inlet 12 is opened to the outside.

Also, in order to open the inlet 2 to the outside as shown in FIG. 2A, when the user manipulates a button switch group or a touch switch group (not shown) which is typically provided in the outer cylinder 2, the storage container 10 is a driving source. It is opened by being raised in linkage with 22.

In the open state of the storage container 10, the cam roller 34 is rolled on the upper surface (the upper portion A of FIG. 4) of the cam plate 8, at which time the arm 30 rotates clockwise. The bottom door 18 closes the lower part of the storage container 10 and waits.

The normal pay-per-use garbage bag E which the user dumps is stored inside the storage container 10 through the inlet 12. According to the lateral dumping method can be strictly limited to the dumpable volume, the user can only dump one pay-as-you-go garbage bag at a time, it will not be able to forcibly push the pay-as-you-go garbage bag more than two times.

When the user crosses the button switch group or the touch switch group that is normally provided on the outside of the outer cylinder 2, the storage container 10 is pulled down by the driving source 22 to descend and the liner of the outer cylinder 2 (4) It is drawn inside. In this process, the cam roller 34 is rolled on the cam plate 8, and the bottom door 18 is loaded with the payload garbage bag E dumped into the storage container 10. The force is applied counterclockwise to the roller 34, but the cam roller 34 cannot rotate counterclockwise because it is supported by the cam plate 8.

When the cam roller 34 moves downward and enters the concave portion formed in the middle of the cam plate 8 (intermediate portion B in FIG. 4), the cam roller 34 starts to rotate by the action of the force applied in the counterclockwise direction. When the roller 34 is located in the recessed portion, the result is the maximum rotation, and as shown in FIG. 2B, the bottom door 18 is completely opened. As a result, the pay-as-you-go garbage bag E stored in the storage container 10 can be obtained. Is handed over to the end pipe of the air transfer waste collection system with a natural fall.

When the cam roller 34 moves away from the recess of the cam plate 8 again and rolls on the lower side (lower part (C) of FIG. 4) by the downward movement of the storage container 10, the arm 30 watches again. Direction and thus the bottom door 18 again closes the bottom of the storage container 10 to be opened and closed once per descent and then maintains the closed state.

As described above, the pay-as-you-go garbage bag injector according to the present invention is a pay-as-you-go garbage bag that is dumped by the action of closing or opening the lower bottom door 18 according to the position of the storage container 10 that is moved up and down by the driving source 22. (E) will be collected.

The middle door B of the cam plate 8 is the time that the bottom door 18 is opened during the lifting and lowering of the storage container 10 is the time when the end pipe of the air transportation waste collection system communicates with the outside. If the length is as short as possible, and the length of the upper portion A is set to be long, actively reducing the time that the end tube side communicates with the outside through the liner 4 can minimize the external emission of the odor.

According to the cam plate 8 shown in this embodiment, the storage container 10 is accommodated in the liner 4 by 1/2 or more, and the bottom door until the trimming panel 14 is close to the upper side of the liner 4. The closed state of (18) is maintained.

In addition, when the upper inclined surface of the middle portion B is set in a hurry and the lower inclined surface is set gently in the cam plate 8, the bottom door 18 is opened quickly and closed slowly, thereby allowing the metering material to be dumped into the storage container 10. The problem of interference due to the closing of the bottom door 18 during the natural fall of the garbage bag E can be solved.
